Sony WI-C100 Wireless In-Ear Headphones

Neckband-style wireless in-ear headphones with physical controls, a built-in microphone, app-based sound adjustment, and up to 25 hours of claimed battery life.

Our take: The Sony WI-C100 is a sensible everyday headset for buyers who want simple controls, a neckband that keeps the earbuds together, and substantial claimed battery life. Its main trade-offs are the less minimal form factor and modest IPX4 protection, while the final comfort, sound, and call performance will depend on ear-tip fit and the listening environment.

What works: Up to 25 hours of claimed battery life, Physical controls for playback, volume, and calls, Flexible neckband helps keep the two earbuds connected, IPX4 splash and sweat resistance, Sound can be adjusted with Sony's companion app
Trade-offs: The neckband design is less discreet than fully wireless earbuds., IPX4 protection is intended for splashes and sweat, not submersion., Call quality and sound can depend on choosing ear tips that fit securely.
